Be it known that I, lViLLiAM S. BULigf Aa citizen of theUnited States,y residing at Greentown, in the county of Howard and State of Indiana, have invented a new and useful Attachment for Floor Surfacers, of which the following is a specification.

This invention relatesto floor surfacing iuachinesand more particularly to attachinents'thereof.

The object of the invention is to provide an attachment for use in taking care of the dust from the edge roller of a floor surfacing machine such as that known on the njiarketas the American universal floor vs'urfa'ging machine and which maybe quicltly trans? fel-red from one side of` the machifne tojthe' other and connected up ready for use by unscrewing and screwing up the stop nut; it being well known that the' edge roller is transferable from one side to the other of the machine. With the foregoing and other objects in view which will ap ear as the description proceeds, the invention resides inthe com-- bination and arrangement of parts and in the ldetails of construction hereinafter described and claimed, it being understood that changes in the precise embodiment o theinvention herein disclosed, may be made within the scope ofwhat is'c'laimed without, departing from the spirit ofthe invention,\v In the accompanying drawings: Figure 1 represents a side elevation of a floor surfacing machine with this improved attachment shpwn applied to the left hand' side thereof.

Fig. 2 is a 'top ment detached; an

Fig. 3 4is a top plan or edge view of the fan housing inlconnection with which the attachment is used with parts broken `out andin section. The machine shown at 1 to which this attachment is applied constitutes no art of thel invention andhence will not e described in detail it bein equipped with the usual side oi' edge ro er 2 and with the' usual fan housing 3. In the ordinary floor lan view o-fthe attachsurfacing machine a dust pan is provided for the-main sanding roller not shown, and

has a suction ipe 5 c'onnectedwith the fan housing 3 wit a discharge p1pe 6 leadingf from said housingv to .the collection receptacle 7 here shown in the vformkovfa bag secured around the discharge endf pipe 6.

porte This inventionA isdesigned totake care of ,the dirt from the side or edge sanding drum or roller. 2 which is Yi'nterchangeably A supporting hanger 13 inthe form of metal strap is secured to the front end of the dust pan -11 and has a laterally Iextending arm 14 at 'its upper end secured by a bolt 15 to a bracket 17. Thisbolt 15 is equipped with a wing nut 16 tofacilitate they attach-v ment and detachment of the attachment or rather of the "support 13.` The L-sha ed bracket 17 has a slot 18 at the outer en of its long arm 'for the passage of the bolt 15 and theshort arm thereof has an open sl'ot 19 forjconnection with the front part of the frame 1 as is shown in Fig. 1.

The suction pipe 10 is equipped with eyes 20. and 21 designedto be connected by links orbra-ces 22 and 23 With the frame of the machine as is shown clearly-in Fi 1 and 2.

These braces 22 andI 23 are use when the attachment is mounted on the left hand side ofthe machine and when it is employed on v"the'righ't hand side suction pipe 10 1s supby -a hook on the frame of the motor. The edge roller. or sanding drum 2 is transferable from one end of the/machine to the other and consequently the dust collecting attachment is made transferable. to -cooperate with the edge roller in either position. The edge sanding drum2 is made slightly lar r in diameter than the main drum, not s own, so that the edges-ofthe door may he finished without the main drum touching the door. To use the edge sandin drumLwhich maybe applied to either en vof the hollow 'shaft of the main drum,

the rod is inserted through the drum 'shaft and the stub end of the edge `roller forced into the drum shaft so that the in engages in the slot -atpthe end of the rum shaft and the washer vis a. pliedto hold it in place. This edge san ing drum is a part of thev American universal door surfacing `machine referred to and constitute'sno part vof this invention. j

The only change necessary to be -made in the 'machine proper when applying this attachment is to provide the .fan housing 3 with the additional tubular coupling 12 for connection of the pipe 10 and when the pipe is not in use this coupling 12 may be closed by a top 24 shown in Fig. 3.

l claim I l. rThe combination with a floor surfacing machine having a fan housing and an edge sanding roll; of a flexible pipe having a. dust pan at one end to be positioned adja= cent said roll', the other end of said pipe being detachably engaged With the fan housing., said 'pipe havingmeans for mounting it on either side of the machine to adapt it for connection with either end ofthe roller when at either' end of the main drum.

roll, the other end of said pipe being de` taohably engaged with the fan housing, Said pipe having ineens for mounting it on either side of the machine to adapt it for connec- Leedeea tion With the roller when at leither end of the, main drinn, said means comprising a bracket connected at one end with the-dust pan, and having a laterally extending arm` at its upper end, and an Lfshaped bracket having an open slot `at 'one end for detachable connection With'the machine frame,

3. An attachment' for door surfacing machines comprising a. exiblepipe having a dust pan at one end-and means at its other end for1 connection with a fan housing, spaced eyes carriedby said pipe, Wires iior engagement with said eyes 'and adapted to be connected with the machine frame to snppoit the pipe intermediate its ends, a bracket risingfi'oin said dust pan carried endl7 and 1 another bracket detachably connected with.

the tiret n'ientioned bracket and having means for connection with the inaohine frame.

ln testimony that l claim the foregoing as my own, l have hereto ased :my signature.
